bug fixes on email program

i am having errors on a program i had done. the program is supposed to allow me to login to yahoos web site and send an email to people on my list of reciepients one at a time via a proxy connection the errors are minor and would peolly take someone a few minutes after going over the code the coder i had develope this for me will not fix it as i already accepted his work prematurely ? so any help would be great?

i still have yet picked a coder on this please review the following and update your bid accordingly or post a message telling me the bid is the same as originally posted and that you are still interested in this project if you are

thank you

"i open the project

start debug

i load the included proxies

i add a yahoo id to send email from in format style

myid(at)yahoo(dot)com:password

then i hit add

i load a list of email addresses to whom i wish to send

i type a subject

i type the body

i then press send message

this is the first error i encountered

it sent the first email but on the next one program stopped responding and the error message from vb was

"NullReferenceException was unhandled"

and code line highlighted was under private sub step6

"[url removed, login to view]("send_top").Focus()"

second error

if i have more then one email address in the list of which email address is being used to send it only will use the first one and if the first one is incorrect it doesnt move to the next email to try it instead it should be able to go to next email if the one its trying to login on wont work

third error

unknown if there is a 3rd or more

i havent been able to test futher with the first error in order to know how many more errors there might be"
